Description

Technical Field

[0001] This utility model relates to the field of FPC technology, and in particular to an FPC gold finger, a gold finger protection component, and a connector. Background Technology

[0002] Flexible printed circuit boards (PCBs) are highly reliable and extremely flexible printed circuit boards made with polyimide or polyester film as the substrate. They are characterized by high wiring density, light weight, thinness, and good bending properties.

[0003] Currently, some automotive projects use plug-in FPC designs. When the plug-in FPC on the automotive display module is assembled into the whole machine, the gold fingers of the plug-in FPC are inserted into the corresponding connectors. The common design of the plug-in gold finger pads is a parallel vertical strip design. However, since the corners of the plug-in end are not covered with copper, the corners are easily impacted during the actual plug-in process, causing the corners to deform and wrinkle, which ultimately damages the FPC plug-in end and is not conducive to the stable application of the FPC itself. To address this, an FPC gold finger, a gold finger protection component, and a connector are proposed. Utility Model Content

[0004] Therefore, it is necessary to provide an FPC gold finger, a gold finger protection component, and a connector to address the aforementioned technical problems. By retracting the outermost gold finger to form a second gold finger and designing a third gold finger in the retracted area, the impact resistance of the corners is increased.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] An FPC gold finger includes an FPC body and a plug-in terminal at one end of the FPC body. A plurality of first gold fingers are provided on the plug-in terminal at equal intervals. A second gold finger is provided on one side of each of the two outermost first gold fingers. An inward recessed area is left between one end of the second gold finger and one end of the first gold finger. A third gold finger is laid in the inward recessed area.

[0007] Furthermore, the third gold finger is rectangular.

[0008] Furthermore, the rectangular third gold finger has a first outer edge and a second outer edge;

[0009] The first outer edge and the second outer edge are both flush with the edge of the corresponding plug-in end, and the connection between the first outer edge and the second outer edge has a rounded chamfer, which is flush with the corner of the plug-in end.

[0010] Furthermore, the rectangular third gold finger also has a first inner edge and a second inner edge;

[0011] There is a gap between the first inner edge and the second gold finger, and a gap between the second inner edge and the adjacent first gold finger.

[0012] A gold finger protection component includes an FPC gold finger and a reinforcing plate. The reinforcing plate is fixed to the back of the FPC body. Side reinforcing portions extend outward from both sides of the reinforcing plate, and gold finger protection portions are installed on the side reinforcing portions.

[0013] Furthermore, the gold finger protection part includes a support shaft fixed to the surface of the side reinforcement part and a support arm movably sleeved on the surface of the support shaft;

[0014] One end of the support arm is fixed with a protective plate. Rotating the support arm on the support shaft allows the protective plate to cover the corner of the plug-in end.

[0015] Furthermore, a fastening disc is threaded onto the surface of the support shaft, and rotating the fastening disc allows its inner side to abut against the surface of the support arm.

[0016] Furthermore, the support arm includes a main arm sleeved on the surface of the support shaft and a secondary arm connected to the protective plate, and an adjusting arm for fixing to the main arm is also slidably provided in the secondary arm;

[0017] A fastening bolt is threaded through the surface of the auxiliary arm, and rotating the fastening bolt will cause one end of it to abut against the surface of the adjusting arm.

[0018] Furthermore, an auxiliary handle is fixed to the surface of the fastening disc.

[0019] A connector includes a gold finger protection component and a connector body;

[0020] The connector body is mounted on and connected to the surface of an external control board, and one side of the connector body has an opening slot. Pushing the plug end can insert it into the opening slot to connect the FPC body with the control board.

[0021] A stepped surface is formed on the side of the connector body away from the opening slot, and the stepped surface can be locked with the protective plate.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] The FPC gold finger, gold finger protection component and connector provided by this utility model, by shrinking the outermost first gold finger to form the second gold finger, and designing the third gold finger in the shrunken area, increases the strength of the corners and improves the impact resistance of the corners, so as to better protect the gold finger of the plug end in the actual plugging process.

[0024] The design of the gold finger protection section allows the support angle of the support arm to be rotated during the time when the FPC body is not plugged in, so that the protection plate can cover the end of the plug-in end. This provides secondary protection. In addition, the design of the rotating fastening plate can leave a gap between the protection plate and the plug-in end below, avoiding direct contact and providing better protection for the FPC body.

[0025] The design of the gold finger protection section allows the support arm to be flipped to release the protection when the connector body is connected and inserted into the FPC body within the slot. After insertion, the angle and length of the support arm can be adjusted so that the inner end of the protection plate is locked onto the stepped surface of the connector body. This can also improve the connection strength between the connector body and the FPC body to a certain extent, ensuring the stability of the FPC body during insertion and preventing the plug from falling off and causing corner bumps.

[0043] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0044] As described in the background section, common connector pad designs are side-by-side vertical strips. However, since the corners of the connector are not covered with copper, the corners are easily impacted during the actual connector insertion process, causing deformation and wrinkles, which ultimately damages the FPC connector.

[0045] To solve this technical problem, this utility model provides an FPC gold finger, a gold finger protection component, and a connector, which are applied to FPC.

[0046] For details, please refer to Figures 1-3 The FPC gold fingers specifically include: an FPC body 1 and a plug-in end 11 located at one end of the FPC body 1. A plurality of first gold fingers 12 are provided on the plug-in end 11 at equal intervals. A second gold finger 13 is provided on one side of each of the two outermost first gold fingers 12. An inward region 14 is left between one end of the second gold finger 13 and one end of the first gold finger 12. A third gold finger 15 is laid in the inward region 14.

[0047] The FPC gold fingers provided by this utility model are designed by indenting the outermost first gold finger 12 to form the second gold finger 13, and designing the third gold finger 15 in the indented area 14. This increases the strength of the corners and improves the impact resistance of the corners, so that it can better protect the gold fingers of the plug end 11 during the actual plugging process.

[0048] For details, please refer to Figures 3-6 The gold finger protection component includes an FPC gold finger and a reinforcing plate 2. The reinforcing plate 2 is fixed to the back of the FPC body 1. Side reinforcing portions 21 extend outward from both sides of the reinforcing plate 2. Gold finger protection portions 3 are installed on the side reinforcing portions 21.

[0049] The present invention provides a gold finger protection component. Through the design of the gold finger protection part 3, during the period when the FPC body 1 is not plugged in, the support angle of the support arm 23 can be rotated so that the protection plate 24 covers the end of the plug-in end 11, thus forming a secondary protection. In addition, with the design of the rotating fastening plate 25, a gap can be left between the protection plate 24 and the plug-in end 11 below to avoid direct contact, so that the FPC body 1 is better protected.

[0050] For details, please refer to Figures 7-9 A connector including a gold finger protection component and a connector body 4;

[0051] The connector body 4 is mounted on and connected to the surface of the external control board 5, and one side of the connector body 4 has an opening slot 41. Pushing the plug end 11 can insert it into the opening slot 41 to connect the FPC body 1 with the control board 5.

[0052] A stepped surface 42 is formed on the side of the connector body 4 away from the opening slot 41, and the stepped surface 42 can be locked with the protective plate 24.

[0053] The connector provided by this utility model, through the design of the gold finger protection part 3, allows the support arm 23 to be flipped when the connector body 4 is connected and inserted into the FPC body 1 in the opening slot 41. This releases the protection while allowing the angle and length of the support arm 23 to be adjusted after insertion, so that the inner end of the protection plate 24 is locked onto the stepped surface 42 of the connector body 4. This also improves the connection strength between the connector body 4 and the FPC body 1 to a certain extent, ensuring the stability of the FPC body 1 during insertion and preventing the insertion end 11 from falling off and causing corner bumps.

[0054] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0055] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0056] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0057] Example 1

[0058] Please refer to Figure 1 , Figure 2 and Figure 3 As shown, an FPC gold finger includes an FPC body 1 and a plug-in end 11 disposed at one end of the FPC body 1. A plurality of first gold fingers 12 are provided on the plug-in end 11 at equal intervals. A second gold finger 13 is provided on one side of the two outermost first gold fingers 12. An inward region 14 is left between one end of the second gold finger 13 and one end of the first gold finger 12. A third gold finger 15 is laid in the inward region 14.

[0059] like Figure 3 As shown, the third gold finger 15 is rectangular, and the rectangular third gold finger 15 has a first outer edge 150 and a second outer edge 151. The first outer edge 150 and the second outer edge 151 are both flush with the edge of the corresponding plug-in end 11, and the connection between the first outer edge 150 and the second outer edge 151 has a rounded chamfer 152, which is flush with the corner of the plug-in end 11.

[0060] The rectangular third gold finger 15 also has a first inner side 153 and a second inner side 154, wherein a gap is left between the first inner side 153 and the second gold finger 13, and a gap is left between the second inner side 154 and the adjacent first gold finger 12.

[0061] In this embodiment, based on the conventional FPC gold fingers, the outermost gold fingers are recessed to form the second gold finger 13, and a third gold finger 15 is added in the recessed area 14. This design of the third gold finger 15 can increase the strength of the corners of the plug end 11, thereby reducing the problem of corner warping caused by pulling and bumping, and thus ensuring the stable plugging application of the FPC1 body.

[0062] Example 2

[0063] Please refer to Figure 4 , Figure 5 and Figure 6 As shown, a gold finger protection component includes an FPC gold finger as described in Embodiment 1, and also includes a reinforcing plate 2. The reinforcing plate 2 is fixed to the back of the FPC body 1. Side reinforcing portions 21 extend outward from both sides of the reinforcing plate 2. Gold finger protection portions 3 are installed on the side reinforcing portions 21. Through the design of the reinforcing plate 2, effective support is provided to the local area of ​​the FPC body 1 at that location. At the same time, since the reinforcing plate 2 itself has a certain strength, it can effectively stabilize and support the gold finger protection portions 3.

[0064] The gold finger protection part 3 includes a support shaft 22 fixed to the surface of the side reinforcement part 21 and a support arm 23 movably sleeved on the surface of the support shaft 22. A protective plate 24 is fixed to one end of the support arm 23. Rotating the support arm 23 on the support shaft 22 can make the protective plate 24 cover the corner of the plug-in end 11.

[0065] The surface of the support shaft 22 is also threaded with a fastening disc 25. Rotating the fastening disc 25 allows its inner side to abut against the surface of the support arm 23. The inner side of the fastening disc 25 can be designed with an anti-slip pad, so that the anti-slip effect can be improved after rotating the fastening disc 25 to abut against the surface of the support arm 23.

[0066] The support arm 23 includes a main arm 220 sleeved on the surface of the support shaft 22 and a secondary arm 221 connected to the protective plate 24. An adjusting arm 222 for fixing to the main arm 220 is also slidably provided in the secondary arm 221. Similarly, an anti-slip pad can also be designed on the side of the main arm 220 facing the fastening plate 25. This, together with the fastening plate 25, can further improve the fixing effect after fastening.

[0067] Among them, a fastening bolt 223 is threaded through the surface of the auxiliary arm 221, and rotating the fastening bolt 223 can cause one end of it to abut against the surface of the adjusting arm 222;

[0068] Specifically, by rotating the fastening disc 25 so that its inner side abuts against the surface of the main arm 220, the overall angle positioning of the support arm 23 can be formed. At the same time, rotating the fastening bolt 223 can also make one end abut against the surface of the adjusting arm 222, thereby positioning the overall length of the support arm 23. When the FPC body 1 does not need to be plugged in, the angle and length of the support arm 23 can be adjusted so that the protective plate 24 covers the top of the third gold finger 15, and a certain gap height is left between it and the third gold finger 15.

[0069] Through the above operations, the corners of the FPC body 1 plug-in end 11 can be further protected, avoiding the third gold finger 15 exposed to the outside from being bumped during the unplugged process, and better achieving the anti-lifting situation at the corner of the FPC body 1 plug-in end 11.

[0070] As a further optimization of this embodiment: an auxiliary handle 26 is fixed to the surface of the fastening disc 25, such as... Figure 7 As shown, the auxiliary handle 26 can better generate rotational drive for the fastening disc 25.

[0071] Example 3

[0072] Please refer to Figure 7 , Figure 8 and Figure 9 As shown, a connector includes a gold finger protection component as described in Embodiment 2, and also includes a connector body 4;

[0073] The connector body 4 is mounted on and connected to the surface of the external control board 5, and one side of the connector body 4 has an opening slot 41. Pushing the plug end 11 can insert it into the opening slot 41 to connect the FPC body 1 with the control board 5. A stepped surface 42 is formed on the side of the connector body 4 away from the opening slot 41. The stepped surface 42 can be locked with the protective plate 24.

[0074] Specifically, when the plug end 11 on the FPC body 1 is inserted into the corresponding connector body 4 through the opening slot 41 to complete the connection between the FPC body 1 and the control board 5, the fastening disc 25 and the fastening bolt 223 can be rotated to adjust the overall length and angle of the support arm 23, so that the end of the protective plate 24 overlaps on the step surface 42. By rotating the fastening disc 25 and the fastening bolt 223, the adjusted support arm 23 is locked, which can keep the protective plate 24 stable on the step surface 42 and prevent displacement.

[0075] The engagement between the protective plate 24 and the stepped surface 42 further secures the connection between the FPC body 1 and the connector body 4, preventing the plug end 11 from being bumped due to loosening and falling off, and further protecting the gold fingers at the plug end 11.
